Introduction
Blood loss is a common and important problem in burn surgery, and patients often require blood transfusions. Preparation of estimated blood transfusions needed prior to surgery is essential. Some studies have devised formulas that can predict blood loss during burn surgery. However, there were many different factors in each study that may influence the amount of blood loss, which were not included in the formulas. Until today, there is no standardized formula that is widely used.
Methods
We searched the Cochrane Central Register of Controlled Trials (CENTRAL) and MEDLINE database for cohort and trial studies that investigate blood loss in burn surgeries. Studies should have clear quantitative blood loss outcome.
Results
We included 15 studies from 1982 to 2018, 13 of which are cohort studies and 2 RCTs, with a total of 1613 subjects; all studies calculated blood loss and assessed possible relating factors, four of them proposed formulas to predict the volume of blood loss, 13 studies mentioned efforts used to reduce blood loss, and 6 studies assessed the timing of surgery. We found trends of blood loss within each variable and summarized them in tables.
Conclusions
From the studies included, there were a variety of results in the amount of blood loss and its related factors. This was due to confounding factors and dissimilarities between studies. However, several studies proposed blood loss prediction formulas, which pose promising benefits to betterment in burn surgeries.
